The content of my user inputted array isn't what was entered

Question

I have a ten spot array in my code, which is user inputted.

for (int i = 0; i < arraya.length; i++){
     arraya[i] = scan.nextInt();
}

After entering

2, 4, 53, 2, 3, 46, 45, 5, 4, 3

the array that was printed read

[I@86b012

How do I fix this?

where is the code of printing array? – singhakash Mar 29 '15 at 17:37 — singhakash, Mar 29 '15 at 17:37

You might be printing array like

System.out.print(arraya); which internally calls arraya.toString() and gives [I@86b012 .

[I - is a class name
[ - an single-dimensional array
@ - joins the string together
86b012 - the hashcode of the object

Source

you have to do

for (int i = 0; i < arraya.length; i++){
     System.out.print(arraya[i]+" ");
}

or

System.out.println(java.util.Arrays.toString(arraya));

Or `System.out.println( Arrays.toString(arraya) );`. – RealSkeptic Mar 29 '15 at 17:44
Arrays cannot be resolved? – GDaniels Mar 29 '15 at 17:53
@GDaniels if you are second method in my answer dont forget to `import java.util.Arrays;` – singhakash Mar 29 '15 at 18:13
Apparently "The import import java.util.Arrays cannot be resolved" – GDaniels Mar 29 '15 at 18:17
I'm not sure what this is for, but I'm using DrJava, and there's no BuildPath under project. – GDaniels Mar 29 '15 at 18:39
@GDaniels use the first method of printing array as given in my answer – singhakash Mar 29 '15 at 18:52
Doesn't that only work inside of the for loop? I want to print it later. – GDaniels Mar 29 '15 at 19:20
@GDaniels check the [demo](http://ideone.com/aOGtvx) – singhakash Mar 29 '15 at 19:30
Like I said, java.util.Arrays cannot be resolved to a type. – GDaniels Mar 29 '15 at 22:40
@GDaniels I have given you the demo with both methods with `seperate loop` and with `Arrays` you can use any one so if second method dint work use the first methods. – singhakash Mar 30 '15 at 04:51

Every java object has a toString() method, and the default method is to display the object's class name representation, then "@" followed by its hashcode. What you're seeing is the default toString() representation of an int array. To print the actual data in the array, you can:

System.out.println(java.util.Arrays.toString(arraya));

Or you can loop through the array like other's have suggested
